Abstract
The utility model discloses a salient pole integral rotor's ten utmost point generators, its structure is: the rotor punching is salient pole whole towards piece, and the excircle adopts eccentric design, and every pole wheel all has the groove of damping strip and the hole of rotor bolt towards the piece, the damping strip is 6 every magnetic poles, and the damping sheet respectively has one at rotor core both ends, and rotor the axial of the screw rod installs between rotor pole body and yoke, and interelectrode support and sharp welding seam are all installed between two magnetic poles. The utility model discloses an advantage: the performance is good, and non -loaded line voltage waveform distortion is 0.77%, and the fully loaded transient voltage regulation of impact is - 10%, recovery time and is 0.7s, and it is + 15% suddenly to unload fully loaded transient voltage regulation, and recovery time is 0.8s to go up the performance requirement that data have exceeded national standard far away, the reliability is high, and rotor winding did not still warp after the generator was worked for a long time.
Description
Technical field
The utility model relates to a kind of generator, especially a kind of ten pole generators of salient pole integrate rotor.
Background technology
In, low-speed diesel engine is little owing to wearing and tearing, failure rate is low, maintenance cycle is long, and the life-span is long, good operation stability, reliability is high, incendivity heavy oil, therefore good economy performance is the main type of Technique For Push Diesel Engine always, and in matching with it, low speed diesel engine generator is widely used.The Fast Construction of boats and ships, is beneficial to the development of marine diesel engine genset industry, and ten pole generators are more and more subject to the favorable comment of vast manufacturing enterprise and user.Ten pole generator numbers of poles are many, and rotor diameter is large, and weight is large, so require that rotor has good intensity, tradition ten pole generator adopts Split-type rotor structure, and this structure fabrication process is complicated, cost is high, and rotor strength is poor, damping stability is poor, also can produce secondary air gap, affects the performance of motor; And usually can add rotor press plate in order to the structural strength ensureing rotor core, the rotor press plate at rotor core two ends makes rotor winding end long and causes distortion, affects the reliability of generator.
Summary of the invention
The purpose of this utility model is ten pole generators providing a kind of salient pole integrate rotor, and this ten pole generator is three-phase brushless synchronous generator, rotor overall convex electrode structure, performance is good, reliability is high advantage that it has.
The utility model is achieved like this: a kind of ten pole generators of salient pole integrate rotor, it comprises rotor core, rotor windings; Rotor windings is wound on rotor core, it is characterized in that: described rotor core comprises rotor punching, amortisseur bar, damping sheet, multi-rotor screw, interpolar support and straight bead, rotor punching is the overall punching of salient pole, cylindrical adopts eccentric design, and every pole wheel punching all has the groove of amortisseur bar and the hole of rotor bolt; Amortisseur bar is every magnetic pole 6, damping sheet respectively has one piece at rotor core two ends, multi-rotor screw is axially arranged between rotor pole body and yoke, interpolar support and straight bead are installed between two magnetic poles, and the acting in conjunction of amortisseur bar, damping sheet, multi-rotor screw and straight bead ensure that the structural strength of rotor core.
Described rotor core two ends do not adopt rotor press plate, and rotor winding end is short.
The utility model has the advantage of: performance is good, non-loaded line voltage-form distortion rate is 0.77%, it is-10% that impact is fully loaded with transient voltage regulation factor, recovery time is 0.7s, dashing forward and unloading fully loaded transient voltage regulation factor is+15%, recovery time is 0.8s, and above data are considerably beyond the performance requirement of national standard; Reliability is high, and after generator works long hours, rotor windings is not still out of shape.

Embodiment
The utility model implements like this: a kind of ten pole generators of salient pole integrate rotor, and it comprises rotor core (1 to 6), rotor windings 7; Rotor windings 7 is wound on rotor core (1 to 6), it is characterized in that: described rotor core (1 to 6) comprises rotor punching 1, amortisseur bar 2, damping sheet 3, multi-rotor screw 4, interpolar support 5 and straight bead 6, rotor punching 1 is the overall punching of salient pole, avoid the secondary air gap of Split-type rotor, the non-uniform gap that the cylindrical of eccentric design produces makes generator waveform good; Amortisseur bar 2 is every magnetic pole 6, ensure that the dynamic property that generator is good; Interpolar support 5 is arranged between two magnetic poles, and the ventilating opening that rotor is formed by interpolar support 5 dispels the heat.
Damping sheet 3 respectively has one piece at rotor core two ends, and multi-rotor screw 4 is axially arranged between rotor pole body and yoke, and straight bead 6 is between two magnetic poles.The acting in conjunction of amortisseur bar 2, damping sheet 3, multi-rotor screw 4 and straight bead 6 four ensure that the structural strength of rotor core, eliminate the rotor press plate at rotor core two ends, not only reduce material, the more important thing is that to make rotor windings 7 end short, the centrifugal force of such rotor windings 7 end generation is when rotated just little, is not easy to be out of shape the reliability that also just ensure that rotor.
Claims (2)
